I only searched shortly for possible duplicates and didn’t found any general such request – so I think that would probably make a good feature request.
But as a remark: I guess there are two opinions on that. E.g. this request is for hiding an element not in use: Show TOTP Copy Button only when TOTP is stored/enabled – and always showing all options (some greyed out) may be a “cluttered UI” for some people.
